GAGING MEANS.

Specification of Letters Patent.

Application filed September 18 1919. Serial No. 8245287.

To all whom it may concern Be it known that I, DANIEL H. JEFFERSON, asubject of the King of Great Britain, residin at Los Angeles, in thecounty of Los Ange es and State of California, have invented new anduseful Improvements in Gaging Means, of which the following is aspecification.

This invention relates to gaging means and more articularly to gagingmeans whereby de nite volumes, as of fluids, may be accurately andexpeditiously gaged as for withdrawal for use from a larger volumerequired is proportionate to the space into which it is to be expanded;as for instance in the fumigation of fruit trees and the lik a tent isplaced over the tree to be fumigated, and after estimation of thecubical space within the tent, the required volume of liquid to beintroduced thereunder is measured by means of the gaging means.

The invention is likewise disclosed in Letters Patent of theUnited-States Number 1,300,170, granted to me the 8th day of April,1919, for gasifying apparatus, in which Letters Patent the same isdisclosed in connection with further apparatus.

With the above and other objects in view, the invention consists in thenovel and useful provision, formation, construction, combination andrelative arrangement of parts, members and features, all as hereinafterto locate the desired opposite notch 16 at 100 described, shown in thedrawings,and finally pointed out in claims.

In the drawing: Figure 1 is a front elevation, partly in section, ofgaging means constructed, organized and applied in accordance with theinvention; and

Fig. 2 is a transverse sectional view taken on the line w a2 Fig. 1. I

Corresponding parts in both the figures are designated by the samereference characters.

Referring with particularity to the drawg, in the embodiment of. theinvention shown thereln, 1 designates a tank orre g' ceiving receptacle,fragmentarily shown,'for

Patented Sept. 7, 1920.

the liquid to be dispensed, 10 designates a pump or gaging cylinderhaving its open upper end 1n communication with the in---" terior of thetank 1; 11 designates a piston in the gaging cylinder 10, 11 designatesa piston rod, and 15 and 16 designate, respec tively, an adjustablegaging stop and means to receive the stop in various positions ofadjustment.

he gaging cylinder 10 terminates at its lower end in a head 10 providedwith a discharge duct 10 in which a check valve 10 is disposed, a seat10 being provided for such check valve. The piston 11 is fitted into thecylinder 10 and has an inlet duct 11 passing therethrough in which ducta check valve 11 is provided. The piston rod 11i's connected at itslower end to the piston 11 and extends therefrom through the tank 1,passing out through the upper head of the tank through a suitablestufiingbox or packing device 12 and is provided with a andle 13 at itsupper end. Below the handle 13 andabove the'tank 1 the piston rod 11 isprovided with the gaging stopshown as the adjustable finger 15 which isslidably mounted upon the rod 11. A collar 15 is secured to the rod 11at a point heneath the fin er and such collar isladapted to contact withthe finger when the piston rod is raised. The means l6'is shown as avertical plate secured to the top of the tank 1 and ranging parallel tothe piston rod. The plate is notched at one of its edges as at 16 andhas a series of alternating long and short pins or prongs 16 at itsother edge, one of the pins 16 bein opposite each notch 16. These pins16 ena le an operator volume of'piston displacement to allow a chargecorrespondingto the size of the tent under which the charge is to 'beplaced to be inducted to the space in the cylinder below the iston.

It will e understood that when the proper notch has been selected theoperator swings the finger 15 into such notch and the finger will limitthe upward travel of the piston during induction, as the collar 15" willstrike the finger 15 when the piston is moved upwardl by means of thehandle 13, so limiting t e amount of the charge of liquid. Upon downwardmovement of the piston to the bottom of the gaging c linder, the correctcharge of the liquid wil be ejected from the pump past the check valve10.

Having thus disclosed nf invention, I claim and desire to secure byetters Patent:

1. Gaging means of the character disclosed comprising a plate having aseries of notches, a stop adapted to be moved into any one of thenotches, a movable gage mem I -ber having a portion adapted to engagesaid stop, and a series of projecting indicating members arranged tocorrespond to the notches and whereby one of the notches may be selectedin the dark by feeling along the projections.

2. Gaging means of the character disclosed comprising a member having aseries of stop-receiving openings, a stop adapted to be received in anyone of said openings, a gaging member having a'portion adaptedforcontact with said stop and whereb the travel-of said gagingmember islimite and a series of means w ereby an operator may by feeling alongthe same locate the required stop-receiving opening.

3. Gaging means comprising a slidable rod, a stop member slidable alongsaid rod, an indicating member having means for coaction with said stopmember whereby the same may be held in a plurality of positions ofadjustment, and means for indicating the position of adjustment of saidstop member; said rod having a portion adapted for contact with saidstop member.

4. Gaging means comprising a movable member, ad ustable stop means onsaid member, and an indicating member adapted to receive and positionsaid stop means in a plurality of positions of adjustment; there beingmeans whereby said movable member is limited in its travel by said 'stopmeans.

In testimony whereoi, I have signed my name to this specification in thepresence of two subscribin Witnesses.
